The theoretical prediction of the value of the cosmological constant is far from being in accord with observations. One way to try to solve this problem is to use a scale invariant theory, however, no standard Lagrangian is truly scale invariant. In this thesis, we try to obtain a scale invariant Lagrangian by adding a suitable counterterm to the Lagrangian for the $ lambda phi sp4$ model. We then apply this technique to different models to see if this method can be applied for very different situations. We also check if flat directions in a scale invariant potential get lifted by renormalization.
